This principle relates to the agenda to hunt the wild story.
When another player spends a moment of awareness to ask a question, the answer you give establishes the truth. Don’t contradict anything we already know (at least, not directly). With each established the truth, the story takes form. If it takes form too quickly, we give it fewer opportunities to surprise and delight us. So choose your answers carefully to not close off too much too soon. Give answers that open new questions and possibilities. Put off making definitive statements until the last possible moment.
